  reveal special inserable items and blocks such as symbols, Math expressions
  and separators.</p>

<p>This feature allows inserting Unicode emoji characters. Simply select
  a category and a desired emoji to insert it.</p>
<p>Emojis can also be searched by their English name and the skin tone can
  be selected via a combo box to the right.</p>
<p>There is also the possibility of inserting emojis directly by typing <code>:</code> followed
  by a name of an emoji, triggering the display of a list of emojis. Simply
  use the arrow keys to select one and press <kbd>Enter</kbd> to insert it.</p>

  <p>Pressing the
    <img src="7_Insert buttons_image.png" width="18" height="15">button will reveal a popup window displaying a list of characters that
    are generally more difficult to insert directly from the keyboard, such
    as a subset of emojis, quotation characters, etc.</p>
  <p>Interaction:</p>
  <ul>
    <li>Click on a character to insert it at the current cursor position.</li>
    <li>The window can be dragged around by the top bar where the title is, to
      avoid it getting in the way of the text.</li>
    <li>Click on the <em>Category</em> selector to filter the characters.</li>
  </ul>
  <h2>Math equations</h2>
  <p>See the dedicated&nbsp;<a class="reference-link" href="#root/_help_YfYAtQBcfo5V">Math Equations</a>&nbsp;page.</p>
  <h2>Mermaid diagram</h2>
  <p>Press the
    <img src="2_Insert buttons_image.png" width="16" height="17">button to create an inline Mermaid diagram.</p>
  <p>This feature is quite similar to the&nbsp;<a class="reference-link" href="#root/_help_s1aBHPd79XYj">Mermaid Diagrams</a>&nbsp;note
    types and is meant as an alternative to it for simple diagrams. For more
    complex diagrams, use the&nbsp;<a class="reference-link" href="#root/_help_nBAXQFj20hS1">Include Note</a>&nbsp;feature
    for a dedicated Mermaid note.</p>

<h2>Horizontal ruler</h2>
  <p>This feature will display a horizontal line, generally useful to separate
    different sections of the text. To do so, press the
    <img src="5_Insert buttons_image.png"
    width="18" height="16">button in the&nbsp;<a class="reference-link" href="#root/_help_nRhnJkTT8cPs">Formatting toolbar</a>.</p>
  <img

    <p>Page breaks provide a way to force the next paragraph or block (table,
      image, etc.) to be displayed onto the next page when printing (either to
      a real printer to <a href="#root/_help_NRnIZmSMc5sj">when exporting to PDF</a>).</p>
    <p>Page breaks are marked in the editor with the words <em>Page break</em>,
      but they will not actually be shown when printed.</p>
    <ul>
      <li>To insert a page break, press the
        <img src="Insert buttons_image.png" width="20"
        height="19">in the formatting toolbar.</li>
      <li>To insert many page breaks at once, insert a page break first, click on
        it and press <kbd>Ctrl</kbd>+<kbd>C</kbd>. Then use <kbd>Ctrl</kbd>+<kbd>V</kbd>,
        to paste as many times as needed.</li>
    </ul>
